Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643078, here are decompositions:

19 + 8643059 = 8643078
89 + 8642989 = 8643078
127 + 8642951 = 8643078
131 + 8642947 = 8643078
139 + 8642939 = 8643078
151 + 8642927 = 8643078
167 + 8642911 = 8643078
181 + 8642897 = 8643078

Showing the first eight; more decompositions exist.
